This project is the Week 2 assignment of the data product coursera course. The project illustrates the work with Maps using leaflet, and the use of R markdown. The data set is the car crash data for the year 2017 in Allegheny County. The data set is taken from this link : https://data.wprdc.org/dataset/allegheny-county-crash-data/resource/bf8b3c7e-8d60-40df-9134-21606a451c1a.
